Application February 24, 1942, Serial No. 432,101

1 Claim.

This invention relates to a novel smoke disperser for pipes or holders,whereby the smoke drawn from a pipe or cigar is so dispersed, whenmoving into the mouth of the smoker, that it will not impinge directlyon the tongue of the smoker in a solid stream. The impingement of asolid stream of smoke on the tongue of a smoker causes irritation;whereas a dispersed or diffused mass of smoke does not cause as great anirritation.

A feature of my invention is to provide a novel and effective means ofdispersing and diffusing the column of smoke which emanates from a pipeor holder.

Another object of my invention is to provide a novel smoke disperserwhich can be mounted or placed in the usual pipestem without materiallydeparting from the usual or well-known construction of a pipestem.

Another object is to provide a novel pipe or holder, smoke disperserwhich is simple in construction, inexpensive to manufacture, andeffective in operation.

A feature of my invention resides in the novel means of controlling aquantity of smoke which is drawn through the stem of the pipe or holderby adjusting my novel smoke disperser in the stem of the pipe or holder.

Still another feature of my invention is to provide a novel smokedisperser which can be efiectively cleaned when necessary.

Other objects, advantages and features of invention may appear from theaccompanying drawing, the subjoined detailed description and theappended claims.

In the drawing Figure 1 is a side elevation of a pipe, illustrating mysmoke disperser in position in the stem of the pipe.

Figure 2 is a longitudinal, sectional view of my smoke disperser.

Figure 3 is an end view of the same.

Figure 4 is an enlarged end view of a pipestem, with my smoke dispersermounted therein.

Referring more particularly to the drawing, the numeral l indicates apipe, which includes the usual pipestem 2. A bore 3 extends from thepipe bowl and through the stem in the usual and well-known manner forthe purpose of drawing smoke from the pipe bowl as will be understood.In the outer end of the stem 2, I provide a smoke disperser 4, whichcomprises a tubular section 5 closely fitting within the outer end ofthe bore 3. A counterbore 6 extends through the member 5, and smoke isdrawn through this counter-bore, as will be further described.

A tapered head I is integrally formed on the outer end of the member 5and the tapered walls of this head are fitted in the outer end of thestem 2. A plurality of grooves 8 are formed in the outer tapered wallsof the head 1, and these grooves communicate with the counter-bore 6 toprovide a continuous duct through which smoke may be drawn. The stem 2is provided with complementary grooves 9 which match the grooves 8 toprovide a substantially tubular conduit or duct. By rotating thedisperser 4 in the stem of the pipe, it is possible to misalign thegrooves 8, 9, thus restricting or reducing the passage through whichsmoke may be drawn; and, therefore, reducing the amount of smoke whichis drawn into the mouth of the smoker. A slot Ill, in the head 1,permits the disperser to be rotated as desired.

In operation the smoke is drawn through the bore 3 in the usual mannerand passes through the bore 6 and the grooves 8, 9, thus drawing thesmoke outwardly from the end of the pipestem, tending to disperse ordifiuse the smoke and preventing the smoke from impinging upon thetongue of the smoker in a solid stream.

It is obvious that my smoke disperser can be used on pipes, cigarholders, or cigarette holders, if desired.

Having described my invention, I claim:

A smoke disperser for pipes comprising a tubular member, circular incross section and of a diameter adapting it to fit snugly in the smokepassage of a pipe stem, a solid head at the outer end of said tubularmember, said head being frustro-conical and tapered toward the tubularmember for snug fit into a flared mouth of the smoke passage of the pipestem, the bore of said tubular member being extended into the inner endof said head, the inner end of the head being formed with radiallyextending smoke outlet openings leading from the inner end portion ofthe said bore and spaced from each other circumferentially of the headwith each opening in opposed relation to another one of the openings,said head being formed with grooves in its annular side surface xtendinglongitudinally of the head in spaced relation to each othercircumferentially thereof from the outer end of the head to the junctionof the head with the tubular member and at their inner endscommunicating with outer ends of the said smoke outlet openings, andsaid head being provided with means for turning the smoke disperser andmoving the grooves of its head intoand out of position to register withcompanion grooves formed in walls of the mouth of the smoke passage ofthe pipe stem.
